MACHINE FOR MANUFACTURING BUTTONS.
SPECIFICATION forming part of Letters Patent No. 536,341, dated March 26, 1 895`.
Application filed August 22, 1894. Serial No. 521,005. (No model.) Iatented in Norway December 29, 1893, No. 3,358, and in England February 3, A1894:, No. 24,964.
To all whom it may concern:
Be it known that 1, HANS CHRISTIAN HAN- SEN, a Subj ect of the King of Sweden and Norway, and a resident of Gjvik, Norway, have invented certain new and useful Improvements in Machines for Manufacturing Buttons, of which the following is a specification.
The invention has been patented in Norway, No. 3,358, dated December 29, 1893, and in England, No. 24,964., dated February 3, 1894.
My invention relates to a machine for manufacturing buttons.
In such machines as hitherto constructed the buttons have been partially prepared in one or more pressing machines, and the parts afterward joined by hand or by another niachine.
The object of my invention is to provide a machine which will completely and continuously manufacture buttons and for this purpose the strips of tinplate or sheet-metal from which the buttons are to be made, are conducted into the machine in two places, one strip on each side of the machine table. The strips are fed by hand into a guiding or feed mechanism, which by means of an arrangement, hereinafter described, conducts the strips in below the punch, which at the same time punches out the parts of the button and the holes in the middle of the same and gives the said parts their required form.
When the punches have punched out the parts of the button the latter are conveyed to an intermittently rotating pressing disk by means of two carriers one of which turns one part of the button so that the side which forms the outer surface of the button comes downward on the pressing disk, while the other conducts the part of the button to the part rst brought, whereupon the .punch above presses the parts of the button together and the ready made button can then be pushed out of the machine.
To enable my invention to be fully underpractice by reference to the accompanying drawings, in which- Figure l is a plan of a machine for manufacturing buttons constructed according to my invention. Fig 1a is an elevation of a devr7 is asimilar view of the other punch.
tail of the same. Fig. 2 is a'section of the machine on the line mex of Fig. 1. Fig. 3 is a section on the line y-y of Fig. 1 showing the press and punch arrangement. Figs. 3 and 3b are sections of details. Fig. 4 is aseotion of the machine on the linee-z of Fig.1, showing one of the carriers. Fig. 5 is a section on the line w-w of Fig. 1. Fig. 6 is a vertical section of one of the punches. Fig. Fig. 8 is an elevation showing the actuating mechanism of the feeding device.
a is a guide plate through which the strip of metal is fed by hand into the machine, it being further guided by the roller a until it reaches the carriage b between the spring plate of which b* (Fig. 8) and the support it is clamped fast (Figs. 1 and 2)'. This carriage which slides in a groove b has a forward and backward movement imparted to it in the direction of the arrows and each y time it feeds a part of the metal strip under the punch arrangement C hereinafter described and shown most clearly in detail in Figs. 6 and 7, whereby a round piece corresponding to the circumference of the button is punched out. Afterward the strip passes into the other carriage b2 which conducts the punched metal strip out of the machine into a receiver or the like. -The clamping of the strip each time it is fed forward is effected by a pawl d, which is keyed toa pivotl doand by means of an arrangement of cranks d', rods d2, and d4 and levers d3 driven from an eccentricd5 (Figs. 1, 2 and 8) on the main shaft c is moved slightly up from and down onto the metal strip at each stroke of the eccentric the arrangement of rods moving the carriages b', bzforward and backward in consequence of the pawl d alternately pressing upon the metal strip and spring plate b* (Fig. 8) so that the crank d is held fast and thereby transfers its further movement to the carriages b', b2. On the other side of the machine is another feeding arrangement b3, b4 exactly like b', bZfor another metal strip from which also -by means of the punch C2 round button-pieces are punched. These two punches C', C2 which will be hereinafter more particularly described diderhowever from each other in that the irst holds the button IOO 5seen piece while the other releases it immediately after the punching. From these punches the button-pieces are conveyed in the following manner.
F is a carrier for the button-piece from the punch C and has three movements, one jumping or upward and downl movement effected by an eccentric g (Fig. 4) with a swell and a notch or depression on the main shaft e, moving up a rod f which is immediately afterward forced down by a spring f2 on the other end ofa connecting-rod f3 The carriage F has also an oscillating movementin ahorizontal plane in the directions of the arrows imparted to it by an eccentric It which com municates an oscillating motion to a leverf4 and this leverflacts upon the spring board or strip f5 which is twisted like aspiral spring round the rod f and by which, assisted by the springf, the rod f is caused to oscillate. The third movement of the carriage is that of the rod f7 round its own axis, caused by the bevel-wheel f3 which gears with the toothed segmentf and during the horizontal oscillating movement of the carriage causes the turning movement of the rod f7. The rod f7 has, as shown in Fig. 1, a four-toothed clawflo, the teeth of which are somewhat tiexible. Each time therod]C7 oscillates in a horizontal plane the said turning and upand down movements take place, so that when the clawflo is under the punching arrangement C', the claws are turned upward at the same time as the rod f is lifted and thereby catches the metal piece punched out in the punching arrangement. Immediately after the rod f7 swinging again in a horizontal plane against the pressing disk I, the rod fT turns so that the claw flo comes down and as soon as this has come above one of the plates t" the rod f receives a push downward with the result that the part of the button being in the claw fw, is spitted on the four prongs i2 on the plate t" which prongs just correspond to the holes in the part of the button.
The arrangement of the two eccentrics g and 7L and the swell and depression of the eccentric gis such, that the up and down, swinging and turning movements of the carriage F take place separately at the proper times as before described. (See Fig. 4.)
The disk I receives an intermittent rotation in the direction of the arrow caused by an eccentric t3 keyed to the main-shaft e (Figs. l and 3) which eccentric through the medium of rods i and i5 and a ball and socket joint i0 causes a rod or pawl '7 to work in ratchet teeth i8 on the disk I. i9 is a spring which keeps the rod or pawl 7 close to the teeth "i8,
rl`he rods or pawls i7 one on each side of the pressing disk I, work intermittently and alternately so that at 'each stroke they separately take up a position against the teeth 'is as shown in Fig. l.
The second carrier F2 is shown in Figs. l and 5 and is placed opposite F but is more simply arranged, it only having an up and down motion and an oscillating motion in a horizontal plane. For actuating it two eccentrics g and h are employed keyed to the main shaft e of which the eccentric g has a notch or depression. The oscillating motion of the carrier F2 with its armjv7 in a horizontal plane, front the punching arrangement C2 to the pressing disk I is caused by an arrangement of rod j', spring j2,'connecting rod j, leverjl, spring band or stripj5 and springjI6 just like that lprovided for the carrier F. As before stated the part of the button punched out in the punching arrangement G2 is released from the punch immediately after the punching and lies on the matrix. When now the arm j? is above the matrix, it receives a push downward through the notch in the eccentric g', by which the prongs on the under side of the arm jT are caused to enter the holes in the part of the button. At the next moment the armjT swings in the horizontal plane against the pressing disk I until the carried button piece is right above one of the plates t" videlicit, above one `of the pieces brought from the pu nchC. The piece brought from thepunch C forms the front side of the button, whil the piece from C2 forms the back.
Both the parts of the button separate from their respective carriers and are kept back on the plates t" by two levers k', k2 (Figs. 1 and 3) catching respectively into the clawfw and the teeth js above the part of the button and at the right moment these levers swing round upon their pivots ko, ko and strike the parts otf the claw flo and teeth js respectively by their free ends receiving an upward stroke from the following rod arrangement shown in Fig. 3. On the main-shaft e is keyed an eccentric Z having two diametrically opposite notches. On this eccentric bear the free ends ICO of two rods 7c3, 7a3 oscilating on pivots it, 7a4 in the rods 15,767 to rock. One of the rods k7 will thereby be caused to slightly push the rod kg, working loose in the machine-table which rod 769 then strikes upward on the free ends of the levers lo', 7a2 as before described. The two parts of the button brought to the plates t" one on top of the other (as shown in Fig. 3d) are now joined or put together so as to form a complete button (as shown at Fig. 3b), by a punch 'm (Fig. 3) with a concave under side. As soon as every one of the plates t" during the intermittent rotation of the disk I (Figs. 1 and 3) has passed beneath the punch m, the latter is carried down byan eccentric n on the main-shaft e and an arrangement of rod fm. and arm m2, the parts of the button being thereby pressed together, as
will be clearly understood by' reference to Figs. 3, 3*, and 3b. By the furthery rotation of the disk I the ready made button is brought under an exhaust tube o and is here vpushed yout of the machine by a rod 7010 working loosely in themachine-table, and actuated from an eccentric Z similarly tothe rod kgand by a similar arrangement k3, 104, 105, k6, k7.
There only remains now to describe the punching arrangements C and C2.
The first is represented at Fig. 6 the body p of the punch being furnished with holes or sockets p2 on each side. Within this body isa punch or die p3 and in the interior of this is a rod p4 provided with pins p5. Securely connected to the body p by screw-threads and a nut p6 is the cutter or punch proper p7 and securely but detachably connected with the die 3 b means of set screws 9, is a rino' .S
the said set screws being also connected with the body p by springs p10. q is thebed or support of the matrix q which together with the punch gives the part of the button its required shape. o" is the table of the machine. When the metal strips are brought in under the punch and the punch descends the cutter p7 first cuts off a small piece, and then the inner punch or die p3 presses theV said piece against the matrix q and forms it of the required shape for the front of the button at the same time that the pins p5 entering corresponding holes in the matrix punch the sewing holes (usually four) inthe part of the button. When now the punch again rises the elasticity or spring of the edge of the button-piece after the punching will cause the button piece to be retained within the cutter p7 until the ring p8 comes against a fork s embracing the body p thereby stopping both the ring ps and the punch p3, which latterV during the further upward movement of the bodyp, willforce the piece outjust at the moment that the claw f1 is immediately beneath it, which claw then takes hold of the buttonpiece and conveys it to the pressing disk I.
It will be understood that the rod p4 carrying the pins p5 is xed to and movable with the block or body p.
The second punching arrangement C2 is nearly the same as C. p is the punch body/ with sockets or holes p2. Inside this punchbody is the punch p3 securely but detachably connected with the ringp8 by screws 1o". Inside the punch p3 is the rod p4 with pinsp5 and the cutterp7 securely connected with the body p', by the nut p, The ring p8 is however here acted/on by a larger downwardlyacting spiral spring p11 and the operation is as follows: When the punch body descends the punch p3 first presses against the metalstrip, but gives Way and acts against the counteractingspringp, until, after thecutter p7 has punched out the round button-piece, it comes against lthe bottom of the body p and in conjunction with the matrix q forms the back part of the button. When the punch-body again rises the punch p3 is re tained alittle on account of the springp11 untilv the cutter p7 has completely released its hold ofthe part ofthe button and the screws pgwith the ring p8 are moved downward in the sockets or holes p2, when the punch p3 also leaves, and the button-part is left on the -matrix whence it is brought to the pressing disk I as before described. The whole machine works accurately and quickly and the product is highly satisfactory.
The punches move in ways shown clearly in plan in Fig. 1, and any well known meansmay be used for operating them.
